a. Draw the first propagation step for a bromide free radical and the double bond of 1-methylcyclohexene. HINT: One electron from the double bond interacts with the bromide free radical to form a new bond. The other electron from the double bond attaches to one of the carbons. Be sure to use three single-headed arrows, and don't forget to draw the two possible free radical products that will form from this step. Circle the most likely product and explain why...

The C-C bond is a single bond and has free rotation about it. Arrange the ethane molecule so that each C-H bond on one C atom is exactly parallel to a C-H bond on the second C atom. (This is the eclipsed position.) View this arrangement by looking along the C-C bond such that the atoms on the front C blank out those on the back C. From this view the model is represented as in 1 (a Newman projection.)...

7. π electron is an electron which resides in the pi bond(s) of a double bond or a triple bond, or in a conjugated p orbital. The 1,3,5-hexatriene molecule is a conjugated molecule with 6 t electrons. Consider the Tt electrons free to move back and forth along the molecule through the delocalized pi system. Using the particle in a box approximation, treat the carbon chain as a linear one-dimensional "box". Allow each energy level in the box to hold...
